I'm looking at Jazz replacement necks and comparing Warmoth with All parts. Pricing is pretty similar so I was hoping someone had experience with both and had an opinion as to which they liked best and why. Thanks.

Hey DR
I've bought 2 Warmoth necks so far to date. Both good quality. One with stainless frets and one without.
I had to spend a little more time on the fret ends on the stainless frets but happy so far. No experience with All Parts sorry.

You want a modern construction neck with alot of wood / inlay / fret options, go Warmoth.

You want a vintage vibe vintage style construction neck truer to original Fender, go with the AllParts. No real options, just pick a model.

Hey greenman, what do you mean about the fret ends? was fret work required on both necks? im looking into building a warmoth soon, and was under the assumption that fret work would not be needed. and also, if anyone knows are the warmoth dinky j bodies similar to the sizing of sadowskys and other boutique jazz basses?

All necks have to be tweaked. Warmoth states that on their site. Yhe stainless frets on my ebony board were a little sharp for my liking. No big deal but expect it.

Warmoth has lots of info on their site about construction and how they have improved the design on their necks to be more stable and longer lasting than the vintage design. All parts doesn't give detail on this.
I'm putting together a fretless J so the frets aren't an issue. I just want the best neck for my money (meaning a solid long lasting neck).

To my mind, the big advantage that Warmoth has over places like Allparts (or even Mighty Mite, who are all required to meet the same quality standards as Warmoth for Fender licensed products - that is, quality in materials and construction that are equal to or better than stock Fender parts) is the variety of woods you have available to you... you are not limited to just maple or maple/rosewood...

You want a modern construction neck with alot of wood / inlay / fret options, go Warmoth.In addition to dual action (adjusts both directions) trussrod, Warmoth necks have twin steel reinforcing rods. This has similar results to the Fender graphite reinforced necks - fewer dead spots - but is heavier (steel is heavy). USA Custom makes a great graphite reinforced neck, but costs a bit more than Warmoth. Warmoth offers an intimidating variety of fingerboard and neck woods, plus a few different inlay options.
Allparts and Mighty Mite use the traditional, non-reinforced Fender design and offer fewer neck and fingerboard wood choices.

Yes, exactly. Thank you...I should have been less vague with what I meant by "modern" construction....

It should also be stated that AllParts necks are made in Japan. I've used both guitar and bass necks from AllParts and they are top-notch.

I know that the OP originally asked about Warmoth and AllParts, but if anyone has any additional info, I would also be interested in how USA Custom Guitars would compare.

I think allparts makes the geddy lee necks used in fenders in Japan because they are identical except the paint on the front and back of the headstock... heck they might do all the japanese necks, idk.

I would also be interested in how USA Custom Guitars would compare.I have not yet used anything from USACG, but I do plan to buy a neck from them in the future. I have talked with them by phone and was very pleased with their obvious knowledge of their products (greater than Warmoth's, in my experience) and the fact that they offer a very broad range of options on their necks (custom widths, thicknesses, radii, others) - than Warmoth does. Check out their website (http://www.usacustomguitars.com/). Although I have not used their stuff personally, many folks who I find very credible have had good experiences with USACG.

I own two USACG jazz necks. One with jumbo frets and one with small ones. Their standard profile for a jazz neck is based on a '64-nice and thin. Just this week, I received an AllParts fretless neck and almost sent it back. Although the workmanship is good, it is a chunkier neck ( 1/16" to 1/8"). I've been spoiled by the USA stuff and will never again buy anything else. Unfortunately it is all custom made to your specs so it takes time. They take the time to do it right.
